Tsab ntawv xov xwm no qhia txog kev hloov pauv ntawm thev naus laus zis, cov qauv kev tshawb fawb, kev siv lub ntiaj teb tiag tiag, thiab kev pom yav tom ntej ntawm MQP cov khoom hloov pauv, qhia tau tias nws tau hloov kho cov qauv kev lag luam li cas.
I. Technological Breakthrough: Los ntawm Kev Txwv ntawm Opticast mus rau Yug ntawm Super Refiner
Txhua qhov kev tshawb fawb tseem ceeb pib nrog qhov kev ntsuam xyuas tseem ceeb ntawm cov kev txawj ntse. Xyoo 2007, Dr. Rein Vainik, xav txog ib xyoo caum ntawm kev ua hauj lwm nrog Opticast txheej txheem optimization tshuab rau grain refinement, tau ntsib los ntawm ib tug hnyav kev muaj tiag: txawm nws cov lus cog tseg, cov txheej txheem ua tsis tau tejyam mus kov yeej qhov teeb meem tsis ruaj tsis khov refinement kev ua tau zoo nyob rau hauv qis ntxiv ntawm Al-Ti-B grain refiners.
Opticast tau tsim los ntawm ib qho kev xav zoo tshaj plaws-kho kho cov nqi ntxiv raws li cov hom alloy thiab cov ntsiab lus seem kom ua tiav qhov kev tswj hwm qis. Txawm li cas los xij, cov neeg siv cov lus tawm tswv yim tsis tu ncua qhia tias qhov qis ntxiv ntawm Al-Ti-B tau ruaj khov rau lub sijhawm luv. Thaum ib qho kev hloov pauv hloov pauv, cov nplej coarsening sai sai ua raws. Qhov kev txiav tawm no yuam kom Dr. Vainik rov mus xyuas qhov teeb meem tseem ceeb. Txoj kev qhia dav dav tau tsom mus rau qhov sib txawv ntawm cov khoom sib txawv, tsis quav ntsej qhov sib txawv ntawm cov nplej refiner lub zog ntawm lub cev. Hauv kev muaj tiag, qhov tsis muaj qhov ntsuas rau ob qho tib si hloov pauv tau hu ua "kev tswj xyuas qhov tseeb" tsis muaj dab tsi ntau tshaj li qhov ntsuas qhov ntsuas.
Qhov kev hloov pauv no tau tsim lub hauv paus rau super grain refiner tus tsim. Hloov ua kom pom tseeb los ntawm aluminium alloy mus rau Al-Ti-B grain refiner nws tus kheej, Dr. Vainik ua cov nplej refinement nkhaus kev ntsuam xyuas ntawm 16 qhov sib txawv ntawm 5Ti1B cov khoom siv Opticast's standardized test protocol. Raws li cov tshuaj sib xyaw ua ke thiab cov cua txias, tsuas yog cov khoom sib txawv. Cov txiaj ntsig tau poob siab - txawm tias cov khoom siv los ntawm tib lub chaw tsim khoom thiab qib tau nthuav tawm ntau qhov sib txawv hauv kev ua kom zoo dua qub. Cov ntaub ntawv nthuav tawm qhov kev mob siab rau kev lag luam ntev ntev: txoj kev Tp-1, siv txij li xyoo 1987, ua tsis tau raws li qhov muaj peev xwm ua kom zoo dua ntawm Al-Ti-B cov khoom.
Nyob rau tib lub sijhawm, MQP tau txais Opticast AB. Tus tsim John Courtenay, paub txog kev ua lag luam cov kev xav tau ceev, tau thov lub tswv yim cuam tshuam: txhawm rau sib koom ua ke Opticast txoj kev ua kom zoo dua qub nrog "qhov muaj peev xwm ua kom zoo tshaj plaws" nplej refiner. Lub hom phiaj yuav hloov los ntawm kev tswj hwm tus nqi ntxiv mus rau kev txhim kho kev ua kom zoo dua qub, hais txog lub hauv paus ntawm kev lag luam cov teeb meem. Qhov kev hloov pauv no tau coj mus rau qhov kev txhais rov qab ntawm qhov tsim tau "kev ua tau zoo ntawm cov nplej refiner." MQP hu nws lub Optifine Super Grain Refiner thiab luam tawm nws cov lus txhais hauv Light Metals Edited los ntawm TMS 2008-cov nplej refiner tus cwj pwm los ntawm lub peev xwm siab tshaj plaws nucleation.
Xyoo 2007 yog tam sim no dav lees paub tias yog lub hauv paus chiv keeb ntawm super grain refiner. Nws cim qhov hloov pauv thaum kev lag luam pom tau hais tias: tus yuam sij rau kev ua kom zoo ntawm cov nplej tsis yog "ntau npaum li cas ntxiv," tab sis "muaj zog npaum li cas lub refiner yog." Nrog rau qhov kev rov tsim dua tshiab no - los ntawm kev paub txog qhov sib txawv mus rau cov ntsiab lus ntawm cov khoom lag luam - MQP tau qhib lub sijhawm tshiab ntawm kev ua haujlwm zoo hauv kev ua txhuas.

Kev tsim kho tshiab kawg yuav tsum muaj kev nkag siab tob txog cov hauv paus ntsiab lus ntawm kev tshawb fawb. Qhov kev ua tau zoo dhia ntawm Optifine super grain refiner nyob rau hauv nws cov atomic-theem elucidation ntawm grain nucleation mechanisms. Xyoo 2021, MQP thiab Brunel University London tau koom tes ua txoj haujlwm tshawb fawb "Lub Nucleation Mechanism ntawm α-Aluminium ntawm TiB₂ Surfaces," muab cov pov thawj tshawb fawb pom zoo rau kev ua tau zoo ntawm super grain refiner.
Siv cov kev daws teeb meem siab kis tau tus mob electron microscopy (HR-TEM), pab pawg tshawb fawb tau tshawb pom qhov tseeb ntawm qhov ntsuas atomic: muaj TiAl₃ atomic txheej nyob rau saum npoo ntawm TiB₂ hais. Qhov sib txawv microstructure no tau nthuav tawm qhov tseem ceeb zais cia tom qab kev hloov pauv hauv kev ua kom zoo dua qub. Thaum muab piv rau ob qhov qauv - ib qho nrog cov txheeb ze refinement efficiency ntawm 50% thiab lwm yam nrog 123% - nws tau pom tias 7 tawm ntawm 8 TiB₂ hais hauv cov qauv ua tau zoo muaj 2DC Ti₃Al interface txheej, thaum tsuas yog 1 tawm ntawm 6 tau ua li ntawd hauv cov qauv ua haujlwm qis.
Qhov kev tshawb pom no thim rov qab txoj kev ntseeg kev lag luam ib txwm hais tias TiB₂ hais ib leeg yog lub hauv paus ntawm cov nplej nucleation. Hloov chaw, MQP txoj kev tshawb fawb tau qhia tias qhov zoo thiab qhov ntau ntawm cov khaubncaws sab nraud povtseg yog qhov tseeb txiav txim ntawm nucleation probability. High-performance super grain refiners qhia tau zoo heev atomic-theem kev txiav txim thiab kev ncaj ncees ntawm lawv TiB₂ hais piv rau cov qauv Al-Ti-B khoom. Qhov txiaj ntsig microstructural no ncaj qha txhais mus rau macroscopic kev ua tau zoo-ntau dua thiab cov nplej zoo dua nyob rau hauv tib qhov sib ntxiv, ua rau cov khoom zoo dua.
Txhawm rau txheeb xyuas qhov sib txawv no, MQP tau tsim ib txoj hauv kev kuaj patented rau Relative Refinement Efficiency (RRE), qhia raws li feem pua. Nws yog xam los ntawm kev sib piv cov qoob loo tsim ib ppm B ib mm³ ntawm cov qauv xeem rau tus qauv siv. Thaum RRE tshaj 85%, cov khoom raug cais raws li Optifine super Al-Ti-B khoom. Qhov kev ntsuas ntau npaum no tsis yog tsuas yog muab lub hauv paus kev tshawb fawb rau kev ntsuam xyuas kev ua tau zoo tab sis kuj tseem ua rau cov tuam txhab lag luam txiav txim siab paub raws li lub zog ua kom zoo.
